That was only a few years ago.
Sunday's competition could result in a much bigger reward.
The first-month professionals are in prime position for one to get his first career victory at a first-time event.
Wolff shot a 9-under 62 on Saturday to share the lead with Morikawa and Bryson DeChambeau at 15 under after three rounds of the inaugural 3M Open.
Morikawa shot a 7-under 64 at the TPC Twin Cities and DeChambeau a 1-under 70.
Wolff, 20, who won the NCAA individual title with Oklahoma State on Memorial Day, is playing in his third event since turning professional, and Morikawa, 22, is playing his fourth. They'll be the final pairing Sunday.
"It's on a lot bigger stage, but our games played very well throughout the spring," said Morikawa, who was named the Pac-12 Men's Golfer of the Year in May while at Cal. "We're going to have to control our nerves, remember who we are, what brought us out here."
"These guys are really good, and I know I'm really good, so it's going to be fun," Wolff said.
A bomber off the tee, Wolff is averaging 306.5 yards through three rounds with his herky-jerky swing. A change in philosophy is allowing that length to be more of an asset.
"The last couple weeks, I think I've been a little too strategic," he said. "I got together this week with my team, and I said, 'You know what, I'm just going to rip driver and just send it.' That's kind of what I've been doing, and it's been working out."
Wolff, who made his professional debut two weeks ago by finishing 80th at the Travelers Championship and missed the cut at last weekend's Rocket Mortgage Classic, added stellar approach shots to help him record six consecutive birdies on Nos. 5-10. None of the putts was longer than 8 feet. Birdies at No. 13 and 15 made a round of 59 seem possible.
However, Wolff missed a 4-foot birdie putt on No. 16, and a tee shot into a bunker led to bogey on the par-3 17th. He scrambled for birdie on No. 18 after an errant tee shot.
"When I birdied 10 to get to 7 under, I was kind of thinking 59, but I kind of knew I had to stay in the moment," Wolff said. "And my caddie, Steve Lohmeyer, he's been really good about that. We talk about, you know, free agency and pretty much anything in between shots to kind of take my mind off of it, which really helped."
Calling his round "pretty much stress-free," Morikawa birdied five of his first seven holes but only three the rest of the way.
"Just hit my lines, hit a lot of good shots and played to my strengths. Ballstriking has been my strength ever since I've been a little kid," he said.
Playing in ideal weather conditions -- temperatures in the low 80s, increasing clouds and no wind -- 65 of the 85 players shot under par on the par-71 layout.
DeChambeau barely did. After his sixth career win and first since the Shriners Hospitals for Children Open in November, he opened the day with a two-shot lead but birdied only the first and last holes to go with one bogey and 15 pars.
"I just didn't make a couple putts that were necessary to give myself that three-, four-shot lead like I should have today," he said.
Sixteen players are within four shots of the lead, including Hideki Matsuyama, Charles Howell III and Troy Merritt, who graduated from nearby Spring Lake Park High School. Each shot a 66 and is two shots behind.
"You always want to come out here right away and have success, but that's really hard to do," said Merritt, 33. "These kids are doing well, and that's good for the game."
